beware: all of the lower end (cheaper) tire carriers have the same issue. they wobble. be prepared to enjoy the sound of a 50lb tire rocking forward and back every time you change speeds, stop, go, hit a bump, go over a rock, etc... i bought a smitty built rear with tire carrier. here is a list of the neat things i learned as a result:
1. you may need a body lift in order to install. (1/2" min)
2. Be ready to drill holes in your frame even if it says "No drill" in the details.
3. don't get one with the grease fitting on top of the hinge, (my tail door snapped it off the second time i opened it)
4. getting the thing closed will require professional wrestling techniques, "Oh speared into the turnbuckle!!" and not good for your jackets.
5. Be ready to relocate your rear view mirror to the top of your windshield, unless you like seeing the awesome tread pattern on your spare and nothing else.
6. Buy an extra wheel spacer so you will be able to actually hang the spare. (i have 10" rims which made it impossible to get the tire on those three studs, $50 later we had my spare mounted. i recommend a 2" spacer.
7. Buy a locking lug nut so someone else doesn't walk off with your spare.
The cheaper carriers are lots of fun, and by fun i mean trouble. the smitty built XRC is spendy but has a much better latching mechanism. the SRC is the same as the one you linked. But all being said even mine still does the one thing they claimed it would...hold my spare tire. The one you listed looks like it mounts to the rear cross member too.
See what's holding his spare and bumper on? Sheet metal...
This idea is rock solid, and doesn'r require a body lift.
Here is a good idea to make the mount stronger
get one of these spacers even if you have normal 8" rims, it makes mounting the spare sooooo much easier.
locking lug nuts are a good idea, at least one for each wheel (all five)
Watch those grease fittings, this one good
This one BAD
Oh and i found this too...
